Serial This invention relates to improvements in indicating mechanism adapted for use with cash'registers and like machines.

The subject matter of this application constitutes a division of the co-pending aipplica tion of the same inventor, Serial No. 527,265, filed January 5, 1922 which issued into Patent No. 1,755,504 on April 22, 1930. f

One object of the invention is the provi sion of mechanism enabling a store selling taxable and nontaxable goods to indicate to the customer the purchase amount of a sale of non-taxable goods, and the total of the purchase amount and tax of a sale of taxable goods.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form'part ofthe specification.

cators provided for this type of machine in that they are constructed to indicate, automatically, the amount of the sale plus the tax assessed thereon, when the article sold is taxable. lVhen no tax is collected, however, the indicators will show just the purchase price of the article.

Keg board and drawing mechanism '26 having bearings .in the side frames. Each of these keys is provided with a notch 30 adapted to cooperate with a. lip 31 on the rear edge of the key coupler.

A rotation shaft 32 (Fig. 2) supported in the side frames is given a complete rotation upon each reciprocation of the key coupler.

The driving means to rotate the shaft 32 includes a roller mounted on a stud projecting from the right hand end of the key coupler, the roller 33 entering a slot 34 formed in a vertical reciprocable double rack 35. At its lower end the rack is bifurcated at 36 to straddle a stud 37 on the right hand side frame. At its upper end the rack is provided wit-h oppositely facing rack teeth 39, which cooperate with apinion 40 fast on the rotation shaft A flange &5 on the side frame cooperates with a flange 46 on the rack to maintain the rack and pinion in mesh. The rack teeth are alternately thrown into and out of mesh with the pinion by a spring 17 and a spring pulled pawl 48;

As is well known in this art, the counterclockwise movement of the key coupler 25, through'the roller 33, raises the double rack 35, and the right hand teeth 39 turn the pinion 410 and shaft 32 counter-clockwise until the coupler 25'reaches the limit of its counter-clockwise movement. At this point, in the operation, the flange 46 has passed upwardly to the leftof the flange 45 and as the former leaves the latter the spring 47,

due to the fact that the point of its attachment to the double rack 35 has been moved above the horizontal center of the stud 37, rocks the double rack to move the flange ill to the right of the flange d5, disei'igage the right hand teeth "39 from the pinion 4-0, and engage the left hand teeth 39 with said pinion. Now, as the key coupler 25 returns, clockwise, to its normal position, the left hand teeth 39 will complete the counterclockwise rotation of the pinion 4:0 and shaft A ratchet or full-stroke disk 4-9 fast to the shaft 32 coop-crates with a :lull-stroke pawl or lever 50, pivoted at 51 to the right hand side frame and held in engagement with the ratchet 4:9 by a spring scatter in a lug- 53 on the right hand side frame, to prevent retrograde movement of said shaft.

Tar kcg/ hen. a taxable article sold, and it is desired to indicate the amount of tax in the machine a. mechanism is provi led which renders the tax indicators e'llective. This mechanism will now be described.

Mechanism is 1n'ovided, as shown in Fig. 5, to retain the tax key, when pushed in, in its tax registering position until the end of the operation of the machine. his mechanism includes a retaining arm 57 provided with a hub pinned to the right hand key coupler trunnion 26. This arm is provided with a downwardly extending finger 58. 1 spring drawn latch pawl 59 is pivoted to the arm 57, and its movement under the influence of a spring 60 is limited by contact with the hub of said arm. An arm (31 pivoted to the side frame at a point 62 slotted to receive a stud 63 carried by the tax key 21. Vv hen the tax key is moved inwa 'dly it rocks the arm (31 counter-clockwise and a flange (ll on the arm 61 strikes and swings the latch pawl 59 until said flange passes a shoulder 65 on said pawl. The spring 60 then snaps the latch pawl 59 to retain the tax key 21 in its depressed position. Now, as the key cou pler 25 rocks com'iter-clockwise, the retaining arm 57 rocked likewise and the latch pawl 59 moved bodily downwardly away from the flange G l oil? the arm 61. hen the flange o l, is released from the shoulder (35 of the ,latch pawl, the arm 61 is rocked clockwise, by the tax key restoring spring (not shown), until the flange 64 contacts the right hand or rear edge 56 of the finger 58 of the retaining arm 57. As the arm 57 continues its counterclockwise movement the flange i l slides along its pivot until the linger :38 of the retaining arm 57 has been raised above the flange 64. At this point in the operation, the flange (ll is no longer restrained by either the retaining linger 58 or the latch pawl 59, and the tax key restoring spring (not shown) restores the tax key :21 to its normal position thus returning the arm 61 to its normal position.

Indicating mechanism Indicating mechanism is provided for indicating the amount of the sale, when no tax is assessed thereon and to indicate the total of the amount of the sale plus the amount oi? the tax, when the article sold is taxable. lhc mechanism for operating the indicators and exposing the appropriate figures with relation to the character of the sale will now be described.

Slidably mounted in guide plates 66 and (37 (Fig. just above the rear end. of each of the keys 20 is an indicator rod (58 which carries at its top one of a series of tablets 69 of a type well known in the art. The ind icator rods are yieldingly held in their lower most positions by springs 70 so that their lower ends are in contact with the rear ends of the keys 20. Each of the indicator tablets 69 bears a special character or characters preferably identical with the character or characters appearing on the forward ends of their appropriate keys, as well as having a character or characters representing the amount represented by that particular key plus the appropriate amount of the tax there for. F or example, the amount 609" is on the upper portion of the indicator tablet associated with the 60 key, while on the lower portion of this tablet is the amount (36 6, this being the previously mentioned amount of (h/l plus the tax ho. hlechanism, which will be described later, is provided to conceal from view either one of the two amounts, depending upon whether the sale registered has been of a taxable or non-taxable article.

It is apparent that the indicator rods 68 will be raised upon depression of their re spective keys 20. Each rod is provided with a shoulder 7 5 to cooperate with a retaining bail 76 which is moved first clockwise as the shoulder is brought towards it to permit the same to pass and release the indicator rods elevated during the previous operation, and then counter-clockwise under said shoulder to support said rod in elevated position. As shown in Fig. 3 this movement is given to the retaining bail 7G by a pitman 77 pivotally connected thereto at one end. and provided at its other end with an elongated slot through which the shaft 32 extends. The pitman carries a roller 78 which cooperates with cam flanges 7'9 and 80 on disk 81 fast on the shaft 32. Springs 82, set between the bail 76 and the guide 66 at each end of the bail, are em- 83 to expose the word Tax.

ployedto hold the cooperating parts on the pitman, shaft, and cam in thelr proper positions. i

Tam and No' tax indicators An indicator 83 (Figs. 2 and 4) is provided for indicating to the urchaser whether or not a tax has been registered in the machine. This indicator is fast on a shaft 84, rotatably mounted in brackets 85 supported by the side frames of the machine. This indicator is of the block type and on two of its opposite faces carries the word Tax while on the remaining two opposite faces are the words No tax. It will be remembered that. the machine, with the parts in their normal positions, is adapted to register and indicate a transaction: in which no tax is assessable, and therefore in the normal positions of the parts the words No tax, as shown in Fig. 4;, will be exposed. When, however, it is desired to register an article on which a tax is assessable the operation of the taxtkey 21 will position this indicator The mechanism wherebythe tax key positions the indicator 83 in either its tax or no tax position willvnow be described. a 7

Fast on the rod 21 (Figs. 1 and 5) of the tax key is an arm 86 carrying the pin 87 cooperating with the forwardly extending arm 88 of a lever 89 pivotally mounted on a shaft 90. A rearwardly extending arm 91 of the lever 89 near its rear end is bent to form a flange 92 slotted to. receive the lower end of a link 93. This link has. a lug 94 (Figs. 3 and 5) located below and in engagement with the under side of the flange 92. The link is also provided with a pair of lugs 95 and between these lugs and the flange 92 is a spring 96 coiled about the link 93. Vhen it is desired to expose the tax indicator to View the tax key is pressed inwardly, whereupon the pin 87 rocks the two-armed lever 89 counterclockwise raising its rear end and the flange 92 thereby compressing the spring 96.

The link 93 is pivoted atits upper end to a bail 76. The link 93 is therefore locked in its lower position until the bail 76 is rocked -1- by the action of the cam 81 as a reg stration is effected, whereupon the spring 96 having been put under tension by depression of the tax key 21. will move the link 93' upwardly until thevbottomof the projection 10! is above the retaining bail'76. The bail 82- (Figs. 2 and 3) theninoves the upper flange of said bail beneath the projection 101 thus re'aining the link 93 in its upper position. rocks the shaft 34v and indicator 83 in coun- The upward movement of the link.

ter-clockwise direction, as seen in Fig. 5, ninety degrees, thereby exposing the faces carrying the word Tax. Near the end of the operation of the machine, the tax key 21 is restored to its normal position by its restoring spring (not shown) as previously points ed out. The link 93, however, is retained in its upper position by. the bail 76, thus leav ing the word Tax exposed to public View until the machine is again operated. Assume, that itis now desired to register a sale of non-taxable goods. The tax key is left in its normal outerposition. The movement of the tax key to normal position during the previous Tax registering operation removes the pin 87 from engagement with the forwardly extending arm 88 on the lever 89. Now, during the instant No tax registering operation, the regular amount keys only, are operated, and when the retaining bail 76 is rocked clockwise by the pitman 77, (Fig. 3), a spring 97 (Fig. 5) restores the lever 89--91 to its normal POSi-w tion, and the flange 92 of the lever arm 91 through its contact with the lug 94 of the link 93, moves said link down toits normal position, thus rocking the arm 100, shaft 84, and indicator block 83 clockwise to conceal the indicia Tax and expose the indicia No tax. l

The machine is provided with a shield 102 (Figs. 1, 2 and 5) for the purpose of-concealing. the indicators from view while the proper one is being brought to its exposed position. This shield is carried by a pair of lifting bars'103guided on studs 104 mounted in the side frames of the machine and projecting through slots 105 in said bars. At their lower ends these bars are bent and have open slots 106, into which the lip 31 of the key coupler projects to raise and lower the lifting bars 103. When one of the keys 20 has been depressed, and the key coupler raised thereby, the lifting bars 103 move the shield 102 to a position to conceal the indicator tablets. At the end ofthe operation, when the keys arerestored to their normal 'positions, theshield 102 willagain be brought to its normal position by the lowering of the key coupler.

An auxiliary shield 107, carried by the shield 102, is provided for normally concealing the lower set of figures on the indicator tablets from view (see Fig. 4). The shield 107 is provided with two legs 108 slotted at 109 to cooperate with studs carried by the lifting bars 103. Studs 114 on the brackets cooperate with slots in the shield 107 to' limit the movement of the said shield; It will be recalled that the lower set'of figures carried by the indicator tablets represents the amount of the sale plus the amount of the tax assessable thereon, and therefore when a sale is made on which-no tax is assessable, it is not desired that these figures be exposed.

However, when a taxable sale is made, it is desired to indicate the total amount of the purchase price plus the tax. Therefore, means is provided for causing the auxiliary shield 107, to be latched in its upper position, and when the shield 102 is lowered, to conceal the upper set of figures on the indicator tablets and expose to view the lower set. The mechanism for accomplishing this will now be described. Fast on each end of the shaft 84 carrying the Tax and No tax indicator is a short arm 115, (Figs. 1 and 5) carrying a pin 116, projecting through a slot 117 in a link 118. These links at their ends are pivotally connected to a pair of latches 119, which in turn are pivotally supported by the pair of brackets 85.

It will be remembered that when the tax key 21 is pressed in, the link 93 is raised by the spring 96 and the shaft 84: rocked counterclockwise (Fig. 5) by the arm 100. As the arms 115 are fast on the shaft 84 the links 118 rock the latches 119 about their pivots a sufficient distance to bring the hooks 120 thereof into the path of pins 121 projecting from the ends of the auxiliary shield 107. It can therefore be seen that, when the shield 102 carrying the auxiliary shield 107 is raised on a tax operation of the machine, the pins 121 will strike the lower faces of the hooks 120 of the latches 119, and as these latches are yieldingly held in the latching po sitions by the springs 96 the pins 121 will rock them clockwise about their pivots a i suflicient distance to permit the pins to pass the ends of the hooks 120 thereof. Vhen the pins have passed the hooks the springs 96 will cause the latches 119 to resume the positions to which they were moved under control of the tax key, and said latches will hold the auxiliary shield 107 in its upper position in order to expose to View the lower set of figures of the indicator tablets representing the amount of the sale plus the amount of the tax.

The no sale key hereinbefore referred to is similar in construction and operation to that of the amount keys. Its operation causes the release of the previously elevated indicator tablets and the exposure of the no sale indicator tablet.

Operation The tax key is normally in its outer position and the machine is in condition to indition of the block indicator 83 and control the upper shield 107 to expose the proper characters on the indicator tablets 69.

Operation of the machine releases the tax key, which is returned to normal by a spring (not shown), and prepares the machine for indicating the value of non-taxable goods upon the succeeding operation, by an operation of the amount keys in the usual manner.
